Downlink UDP Test

Introduction

The purpose of the Downlink UDP Test is to measure the downlink receiver
performance of a Mobile WiMAX subscriber station (SS).

Upon establishing two way communications, control and broadcast messages
are transmitted between the E6651A and the SS, though no user traffic
is present. The E6651A can test the receiver performance of the SS by
transmitting user data in the downlink direction. In the DL UDP test,
the load is applied in downlink direction only, with only short acknowledgement
messages sent on the uplink.
